- Fundus, retinal: The interior lining of the eyeball, including the retina (the light-sensitive screen), optic disc (the head of the nerve to the eye), and the macula (the small spot in the retina where vision is keenest).he fundus is the portion of the inner eye that can be seen during an eye examination by looking through the pupil. Fundus is the Latin word for the bottom. In medicine, fundus refers to the bottom or base of an organ.

Definitions &Translations Pupil. The pupil is a hole located in the center of the iris of the eye that allows light to enter the retina. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.

The Anatomy of the Eye The eye is essentially an opaque eyeball filled with a water-like fluid. In the front of the eyeball is a transparent opening known as the cornea. The cornea is a thin membrane that has an index of refraction of approximately 1.38. The cornea has the dual purpose of protecting the eye and refracting light as it enters the eye. After light passes through the cornea, a portion of it passes through an opening known as the pupil. Rather than being an actual part of the eye's anatomy, the pupil is merely an opening.

What's that Ring Around My Eye? Corneal Arcus, sometimes referred to as Arcus Senilis in an older patient, is a greyish or yellowish opaque colored ring or arc around the peripheral cornea of both eyes. The corneal arcus ring consists of lipid/cholesterol deposits in the periphery of the cornea stromal layer.

Eye Anatomy: How Do Our Eyes Work? Vitreous humor makes up approximately 80 percent of the volume of the eyeball. It is a gel-like substance in the back part of the eye that provides the shape of the eyeball. The vitreous humor is located between the lens and the retina, in an area called the vitreous cavity.Besides helping to maintain the shape of the eyeball, the vitreous cavity also provides a clear pathway for light going through the eye to the retina. The Aqueous Humor is the watery region in the front of the eyeball.itreous humor makes up approximately 80 percent of the volume of the eyeball.

Retina the innermost of the three tunics of the eyeball, surrounding the vitreous body and continuous posteriorly with the optic nerve. The retina is composed of two parts: an optical part in the fundus of the eye that is sensitive to light, and a nonsensitive pigmented part that lines the ciliary body and iris.

Eye health guide Pterygium is a growth that develops across the clear cornea of the eye that can affect people who spend a lot of time outside in the sun. The pterygium is usually pink and fleshy and forms on the side of the eye nearest to the nose. Pterygium can cause discomfort, and interfere with vision if the growth is allowed to continue.

- Its optical design is based on the indirect ophthalmoscope. Fundus cameras are described by the angle of view - the optical angle of acceptance of the lens. An angle of 30°, considered the normal angle of view, creates a film image 2.5 times larger than life. Wide angle fundus cameras capture images between 45° and 140° and provide proportionately less retinal magnification.

The Cornea The anterior chamber of the eye is filled with the watery aqueous humor which has an index of refraction of about 1.336. It is positioned immediately behind the cornea. The larger chamber of the eye is filled with the gelatinous  vitreous humor , which has an index of refraction of about 1.337.

Vision (eyesight): What does spherical, cylindrical, and axis mean in an eyeglass prescription? OD is thus right eye. 1  The cornea is the outer cover of the eye's hole allowing light in. 2  The iris is the muscle that pulls the opening in the eye (the pupil) open (the coloured bit).  The lens is like an internal pair of glasses that focuses the light that comes through the cornea onto the retina.

What Is the Fundus of the Uterus? What is a normal size for a uterus and ovaries? The fundus is the topmost portion of the uterus and is known as the roof of the uterine cavity. During pregnancy, this is usually when the fertilized egg implants. The fundus and uterus can stretch significantly throughout pregnancy without any trauma or damage. Throughout pregnancy the uterus grows to make room for the growing fetus. Doctors check the fundal height, or the top of the fundus, through gentle pressure on the abdomen to ensure that the pregnancy is progressing correctly.

Orbicularis Oculi Muscle Orbicularis oculi (pronunciation: or-bi-kyu-LAR-is OK-yu-lai) refers to the muscle around the eyes. Its origin is the medial side of the orbit and the insertion is the path that circles the orbit.ars orbitalis or the orbital part of orbicularis oculi is the bulkiest among the three. Coarse fibers surround the entire orbit. It has two origins: the frontal bone and the maxilla. The insertion circles around the orbit.

Fundus photographs of the right eye (left image) and left eye (right image), seen from front so that left in each image is to the person's right. The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disk is located towards the nose. The macula or macula lutea (from Latin macula, spot + lutea, yellow) is an oval-shaped pigmented area near the center of the retina of the human eye. It has a diameter of around 5.5 mm. The macula is subdivided into the umbo, foveola, foveal avascular zone (FAZ), fovea, parafovea, and perifovea areas.

As the only complete layer, it provides protection to the inner mechanisms of the eye, helps it hold its shape and provides a surface for the attachment of the muscles responsible for moving the eye.tructure of the Eye. The eye is divided into three main layers. The main, outer layer is the fibrous tunic and is the only complete layer in that it encircles the entire structure of the eye. The middle layer is the vascular tunic, a network of blood vessels that provide oxygen and nutrients to the eye's tissues.
